An E6B flight computer is a vital pilot's tool designed for calculating various flight parameters, including groundspeed, fuel burn, time en route, and density altitude, by aligning values on its ...

Pressure altitude is an aircraft's height above a theoretical "standard datum plane," defined by specific atmospheric conditions (29.92 inHg pressure, 15°C at sea level). It is a critical metric for ...

A common question arises: can density be determined using the free space measured on a gas adsorption analyzer, rather than a device specifically designed for density measurement? This article ...

The units of density depend on the units used for mass and volume. The most commonly used units are grams per cubic centimetre (g/cm³) or kilograms per cubic metre (kg/m³). These balloons are the same ...

A study on predicting acid-gas densities for the pressure and temperature ranges relevant to acid-gas injection schemes found that only one common equation of state gave unsatisfactory results.

This note considers the computation of the content and the boundary of the highest posterior density region in the context of data augmentation. The notion of the highest posterior density region and ...
